After the commissioning of the EC-30C, the temperature diagram starts adding measure-
ment readings from right to left. Every three minutes the characteristic line is updated with
a new temperature value. The diagram always shows the measured temperature of the
last 6 hours. Temperature values older than 6 hours will be deleted.
The y-axis of the PCU temperature diagram shows a temperature range from -35 °C to +25
°C (~-31 °F to +77 °F). Measured values exceeding or going below this temperature range
will not be displayed.
